Answer: Yes, we can easily make them. Please contact us directly for more information.

Will it stick to non slip textured surface on the gunnel/gunwale?

Answer: Yes, it will stick nicely. Just understand, when it's time to remove, it will be a job getting it off of the non-skid. This backing tape is serious stuff.

Tube of adhesive for seadeck

Answer: Does not come with tube, peel of self adhesive to attach

Answer: Self sticking. No glue needed.

Answer: No

Which one is the light gray with the black lettering? Thanks

Answer: If you select the option that says cool gray over black that would be the one you're looking for.

How thick is the foam? Does it hold up well to cleaners with bleach? Color fade or foam degrade?

Answer: These rulers are 6mm thick which is right around 1/4" thick. It holds up well to cleaners with bleach, but best not to use straight bleach on the material. Although it doesn't hurt it immediately over time it can begin to degrade the material.

Answer: Thick enough. And nope doesn’t fade with bleach nor degrade. Great product and easier to clean than I would have thought

What's the difference between this $45 seadek and the $25 seadek also listed on amazon?

Answer: Our SeaDek rulers are 6mm thick and have routed inch marks as well as two-tone color options. The other SeaDek rulers are 3mm thick and single color options with lasered inch marks. Hope this helps and feel free to reach out to us directly if we can assist you further!

Is this permanently on boat or can it be easily removed?

Answer: It’s meant to stick but can be fairly easy to removed

Answer: It can be removed but carefully so you can reapply in another location

How is ot with fading? Does the foam get dry and degrade? Does it get cut easily by the fins and scales? Does the tape stick well and hold?

Answer: I’ve had this on our boat for over 6 months now, no fading or cracking, foam still looks and feels as if we just got it, no cuts or anything from any of the fish we’ve put on it and the adhesive they use holds so well I don’t even think a grizzly bear could pull it apart

Answer: Looks amazing. Great holding power. Too early to respond to other questions. Only installed 3 weeks ago.

Answer: So far so good! Looks great and is holding nicely!

Are the measurements correct for legal size?

Answer: The pads are all CNC cut so they are accurate as long as the pad isn't stretched during installation.

Answer: Yes they line up

Answer: Yes
